This. If temps are in the low 20s sun angle hardly matters. You might lose a very small amount to it. 

Seen it plenty of times in our prime backloaded winters. Snow otg in early March survives nicely when temps are in the mid to upper 20s on a sunny day. Ofc at most that lasts one day.

It could use a 50/50 low

Hence "pretty much". Nice catch by the way. :)

Edit: Those higher heights are really just an extension of the Baffin block. Not really an issue. Although we are parsing day 8 maps because we are weenies. 

Edit #2: That really reminds me of 2010.

Couple interesting - AO records broken for the first half of December.  

 

Posted this evening from Don Sutherland:

The preliminary Arctic Oscillation (AO) was -3.216 today. December 1-15 has experienced the strongest AO block on record for the first half of December. The AO averaged a preliminary -2.908 (old record: -2.138, 1985) with 8 days at or below -3.000 (old record: 6 days, 1966).

You do know we got several feet of snow from one storm in 2016

40 inches here. But who's counting? In all seriousness. Having both major globals with pretty similar setups is probably a decent sign someone is going to get smacked. Might not be all of us. Always depends on track. Off the coast is good for coastal plain dwellers. On the coast and I am dancing. But I think it is pretty likely there is going to be a big storm somewhere on the east coast at this point.

@psuhoffmanif trends continue can we get a live stream at some point for one of the model runs? 

If we can get it inside 5 days sure. But we’re way too far out at this point. I wouldn’t mind doing just a general pattern overview chat at some point either though.  I’ll be honest though I don’t have as much time as I used too.   So if I’m ever unable to host and anyone else wants to take over I’m great with that. But I’ll try to fit them in when warranted.
